Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 1145.05 g/mol gives Tenapanor Impurity 3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Tenapanor Impurity 3 (CAS CATO-C4X-32333) is a certified pharmaceutical impurity reference standard with the molecular formula C50H66Cl4N8O10S2 and a molecular weight of 1145.05 g/mol.
The molecular framework of Tenapanor Impurity 3 (C50H66Cl4N8O10S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
As a certified reference material (CRM), Tenapanor Impurity 3 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
